But from a grammatical sense it’s the opposite. In a sentence, a comma is a short pause, while a period is a hard stop. That means it makes far more sense for the comma to be the thousands separator and the period to be the stop between integer and fraction.

I’d like to know the same. I really like the RP2040 and use it often, looking to move to the RP2350 but the GPIO issue is holding me back.
